Good afternoon,
After 100 years of manned flight designers are still learning from birds. An interesting article in December's National Geographic discusses a futuristic cargo plane called the Pelican. Although still a concept, the idea was conceived by watching pelicans glide across the waves almost touching the water with their wingtips. As we birdwatchers already know the pelican is certainly one of the most aerodynamic of all birds.
